| Abstract: |
| The properties of vulcanizates of trans-1，4-polyisoprene（TPI）and its blends with BR，SBR or NR were studied. The results showed that the excellent mechanical and dynamical properties were obtained by controlling the sulfur level，that is crosslink density；the blends of TPI with BR，SBR or NR featured good processibility；the mechanical and dynamic properties of TPI/BR，TPI/SBR or TPI/N R vulcanizates were better than those of BR，SBR or NR vulcanizates when the blending ratio was lower than 50/50，in particular the tension fatigue property，which was just the property needed by performance tire，improved signifcantly. |
